      </span></p><p align="left"><span style="FONT-SIZE: 10pt">As one professional Broadcast-Grade digital QAM agile modulator, QAM2300is designed to receive DVB TS stream signal from other digital headend devices, for example, DVB multiplexer, Video Server, MPEG-2 video/audio encoder, digital TS receivers, or SDH network; Then outputs and amplifies DVB-C RF signal to the desired CATV system channel with agile frequency in the range of 50MHz to 860MHz with adjustable level.<br />
      With its perfect performance and high stability and reliability, QAM2300 is very suitable for various digital broadcast systems, including digital CADTV/MMDS system, HFC broadband network system, DVB data broadcast and VOD system.<br />
